Current was minimal, but not in the ship's favor. This was all about the momentum of a 150,000 ton ship at 7 kts, losing steerage less than a 1/2 mile from the bridge.Back to the currents and river flow then, and this verses weight, flow of current either inward or outward in the inlet, and excetra, excetra.
In the old days, tugs used to be powered by Atlas Imperials. They were also direct drive- to put it in reverse you shut down the motor and started it up in reverse.
The rule when coming into the dock was if the engine didn't re-start, you aimed for another company boat. If there was no company boat to crash into, you aimed for the cheapest boat at the dock.
